Parking Lights won't turn on with either switch on the steering column. Head/reverse/break/fog lights all work.

Checked/replaced fuses. Bulbs look fine, just don't know if their is a relay etc that could go bad.

Wondering if anyone else has had experience with this problem and can hopefully shed some light on my dismay.

Thanks for your time.

 

Today I pulled the column switches out and jumpered the red/black wire to the orange wire leading to the rocker switch with no luck. Also tested every single fuse (since I was there already). Noticed that now my fog lights no longer work which is a new problem.

Also verified that I was getting current to that plug. I'm assuming that goes through the illumination control unit? Or is that relay only for interior lights?

Anyone have some insight?
